SEAL.

Specification of Letters Patent.

Patented May 18, 1915.

Application filed April 20, 1914. Serial No. 833,068.

To all whom it may concern Be it known that I, PHILIP J. MITTEN, acitizen of the United States, residing at Oakwood Village, in the countyof Montgomery and State of Ohio, have invented certain new and usefulImprovements in Seals, of which the following is a specification,reference being had therein to the accompanying drawing.

This invention relates to seals such as are employed for preventing theremoval of fastening devices by means of which two parts are fastened orlocked together and is more particularly designed for use in connectionwith fare boxes to prevent the removal of the top of the case, whichwould permit of access being had to the interior of the box. The sealcommonly in use for such purposes consists of a wire having its endsbrought through an opening in a lead disk which is then compressed onthe ends of the Wires to retain them in position and prevent thewithdrawal of the wire from the fastening device through which is hasbeen passed. In practice, however, some unscrupulous persons have beenable to loosen the wire in the disk and remove the same, thus releasingthe fastening device, and to subsequently return the ends of the wire tothe lead disk and re store the seal to its normal appearance.

The object of the present invention is to provide a seal of thischaracter which cannot be removed or separated to permit the fasteningdevice or devices to be removed without destroying the seal or a partthereof; and further, to so construct the seal that the broken ordestroyed part thereof cannot be readily duplicated and the duplicatepart substituted for that which has been destroyed.

To this end it is a further object of the invention to provide a seal inthe form of an elongated bar made up of two or more parts, the adjacentends of the parts being connected one to the other by pressing a portionof one part into a recess in the other part, and so arranging the partsthat a lengthwise movement sufficient to separate them cannot beimparted thereto without destroying one of the parts, thereby preventingthe parts being separated by a lengthwise pull.

In the accompanying drawings Figure 1 is a plan view, partially brokenaway, of the top of a fare box. Fig. 2 is a side elevation of the upperportion of a casing forming a part of the fare box and the top for thatcasing. Fig. 3 is a plan view of the seal and fastening devices. Fig. iis a detail sectional view of one end of the seal and one of thefastening devices. Fig. 5 is a detail view of the blank from which onepart of the seal is formed.

In these drawings I have illustrated one embodiment of my invention andhave shown the same as applied to the casing and top of a fare box, butit will be understood that the invention is capable of being applied notonly to difierent parts of a fare box where it may be desired to use afastening device, but also to any other device in which it is desired toseal the fastening devices against removal.

In the accompanying drawings a portion of the casing forming a part ofthe fare box is shown at 1 and secured to the end of this casing is atop piece 2. These structural parts of the fare box form no part of theinvention and are shown here merely to illustrate the fastening devicesand the seal. The top may be secured to the casing 1 by the use of anysuitable fastening device. In the present instance the top is providedon one side with a depending lug 3 having a projection 4 adapted toenter a hole 5 in the upper portion of the adjacent wall of the casing.In the present instance the projection 1 is in the form of a studmounted in a hole in the lug 3, having its end upset after the manner ofa rivet and having an enlarged head forming the projection and taperedto facilitate its entrance into the hole 5. As here shown I haveprovided this side of the top with a single lug and fastening device,but obviously any suitable number of these devices may be employed. Theopposite side of the top is provided with one or more lugs 6. In thepresent instance I have shown two. These lugs are adapted to extendinside of the adjacent wall of the easing and after the projection a hasbeen placed in the hole 5 and the lugs 6 moved into their positionswithin the adjacent wall of the casing, it will be impossible to removethe projection 4 from its opening without first removing the lugs 6 fromtheir positions within the casing. Suitable fastening devices areprovided to retain the lugs 6 in their positions within the casing.Preferthreaded pins.

these portions of the pins are provided with ably, but not necessarily,these fastening devices are of such a character that rotatory movementis necessary to their removal and to the releasing of the lugs 6.

The particular form of fastening device here'shown comprises ascrew-threaded pin 7 having an enlarged head 8 and adapted to extendthrough an opening in the wall of the casing 1 and to be screw-threadedinto a screw-threaded opening in the lug 6 until the head 8 is broughtinto contact with the Wall of the casing. So long as the parts remain inthis position it is impossible to separate the top from the casingwithout destroying one or the other of these parts.

To prevent the removal of the fastening devices a locking device orsealis provided which will prevent therotation of the screw Preferably thisseal is in the form of a bar or rod extending between the two fasteningdevices, where twonsuch,

vention here illustrated the enlarged-headS of each fastening device isprovided with a transverse aperture 9 through which extends a pin 10forming a part of the seal. pin has a head 11 to limit its lengthwisemovement in one direction and the aperture 9 is enlarged at its outerend, as shown at 12, to receive this head. Preferably the head isrounded as shown in the drawings to prevent it being grasped by a pairof pliers or other implement. The inner end of each pin 10 projects somedistance beyond that side of the fastening device opposite the enlargedportion 12 of the aperture, and

recesses 13 which, in the present instance, are in the form of annulargrooves having a relatively great width. Arrangedbetween the twofastening devices and connected with the inwardly projecting parts ofthe pins 10 to form the intermediate portion of the seal is a rod 14having its ends hollow to receive the adjacent ends ofthe ins 10.Preferably this rod is in the form of a tube,

of brass or other ductile material, andisof a length but slightly lessthan the distance betweenthe two fastening devices. Infplacing-the sealin position it is necessary that the intermediate portion or ductilebody 14' should be first placed in position and then the pins insertedin the apertures 9 in. the fastening devices and thrust in to. the adj a"55 cent ends of the tubular body. 'Afterthe The,

This

parts have been assembled in this position those portions of the tube'orbody which extend about the recesses 13 are compressed the seal. It willbe obvious that after this by means of a suitable implement to force themetal thereof into the recesses, thus firmly connecting the pins withthe body of connection is made it will be'impossible to rotate either ofthe fastening devices without destroying the seal. The ends of the bodybeing arranged close to the respective fastening devicesprevents theheads of the:

pins being moved outward into a position in which they could be grippedand a lengthwise pull exerted thereon. Likewisethis arrangement of thebody 14 prevents longitudinal thrusts being exerted upon this body insuch a manner as to gradually loosen the grip of the compressed portionsthereof on the pins. By making the recesses-or'annular grooves 13 of awidth greater thanthe compressed portion of the. tube or bodyit is notonly easier to locate the recess and press the metal intov the same,butthe tube may have. a slight longitudinal movementlon the pins withoutbringing the compressed portions thereof into engagement with theshoulders at the ends of the recesses, which engagement would, ifrepeatedly made in a forceful manner, gradually force out thecompressedportions of the-tube. To prevent a duplicate of the ductilebody or tube 14 being provided by unauthorized persons and substitutedfor the tube of the seal after the latter hasfbeen broken, I prefer toprovide the tube with a distinctive marking which is engraved, punched,-or otherwise formed therein as shown at 15 and which it would bedifficult to duplicate. Moreover,

the implement employed to compressor crimp the material of the tube intothe re.- cess may be of such a character asto form a distinctive mark,as shown at 16, which mark- 7 it would be difiicult to duplicatewithollithe use of this particular tool.

The operation and manner-of use of the. device will be readilyunderstoodfrom'. the

foregoing description and itvwill be apparent that thedevice'willveffectually prevent the removal of one'or both fastening de;

vices without the destruction of some part, of.-

the seal. Further, that the; device is 'of a simple, inexpensivecharacter which canbe readily applied to the fastening {devices It willalso be apparent-that while I have shown the seal as applied to twofastening devices it will operate equally well with a single'fasteningdevice by providing a suitable support for that end of the seal oppositethe end connected with the fastening device, to take the place of thesupport formed by the other fastening device. Further, it will beapparent that the ductile tube. or body'may be formed in any suitablemanner,

as by using a section of drawn tubing or 180 by die casting, but in thepresent instance I have formed the same from a blank of metal, whichblank is shown at 17 in Fig. 5, and is adapted to be bent into the formof a tube.

'While I have shown and described one embodiment of my invention, itwill be understood that this has been chosen for the purpose ofillustration only and that I do not wish to be limited to the details ofconstruction shown and described, for obvious modifications will occurto one skilled in the art.
